Ive come to one main conclusion: Insurrection killed off future buzz for STNG movies. There was a good ad campaign, the cinemascore was fine from people who went ro see it, but the tv and film franchise was faltering somewhat in the eyes the general public and non-trekkie fans.
I agree with this. Have always thought it unlikely any casual fan subjected to INS (a TV episode, and a very, very poor one at that) would ever willingly part with their money to see another Next Gen film.
